Abstract :
An overview of components designed and implemented in the PolyStrata micro-coaxial technology at millimeter-wave frequencies will be presented. The components are designed and characterized at the University of Colorado, and fabricated by Rohm and Haas Electronics, in collaboration with BAE Systems. Micro-coaxial air-filled cables with purely TEM propagation up to 450 GHz are fabricated using sequential deposition of 5 to 11 layers of copper, and used to implement couplers, hybrids, Wilkinson dividers/combiners, impedance transformers, etc. from microwave frequencies to W band. Some advanced concepts for THz components are also achievable in this technology.
